Demand Response System and Method for Controlling Devices to Participate in Demand Response Automatically

1. A demand response method comprising: determining priorities of devices to be controlled to participate in a demand response; generating respective participation profiles for the devices based on the determined priorities; and changing the priorities of the devices included in the participation profiles, based on whether participation in the demand response according to the generated participation profiles succeeds, wherein the determining the priorities comprises: extracting user preference profiles of the devices through machine learning by using past using histories of the devices in a specific space, the user preference profiles comprising a first user preference profile corresponding to a first user of at least one device of the plurality of devices in the specific space and a second user preference profile corresponding to a second user of the at least one device in the specific space; and determining the priorities of the devices based on the first user preference profile or the second user preference profile based on which of the first user or the second user is in the specific space at a time of the demand response, and wherein generating the respective participation profiles for the devices comprises: receiving outdoor temperature data; and generating, for at least one of the devices, a first participation profile having a first energy savings rate based on the outdoor temperature being greater than or equal to threshold value and a second participation profile having a second energy savings rate greater than the first based on the outdoor temperature being less than the threshold value.

2. The demand response method of claim 1 , wherein the changing the priorities comprises, when the participation in the demand response according to the generated participation profiles succeeds, increasing the priorities of the devices included in the participation profiles by at least one step.

3. The demand response method of claim 1 , wherein the changing the priorities comprises, when the participation in the demand response according to the generated participation profiles fails, dropping the priorities of the devices included in the participation profiles by at least one step.

4. The demand response method of claim 1 , further comprising identifying whether the participation of the devices in the demand response is accepted in sequence according to the priorities until a target amount of energy savings required in the demand response is satisfied.

5. The demand response method of claim 4 , further comprising modifying the priorities of the devices based on whether the participation of the devices in the demand response is accepted.

6. The demand response method of claim 5 , wherein the modifying the priorities comprises, when a device gains an acceptance of participation, increasing the priority of the corresponding device by at least one step.

7. The demand response method of claim 5 , wherein the modifying the priorities comprises, when a device does not gain an acceptance of participation, dropping the priority of the corresponding device by at least one step.

8. A non-transitory computer-readable recording medium having a computer program recorded thereon that, when executed by a processor, cause an apparatus to perform a demand response method, the method comprising: determining priorities of devices to be controlled to participate in a demand response; generating respective participation profiles for the devices based on the determined priorities; and changing the priorities of the devices included in the participation profiles, based on whether participation in the demand response according to the generated participation profiles succeeds, wherein the determining the priorities comprises: extracting user preference profiles of the devices through machine learning by using past using histories of the devices in a specific space, the user preference profiles comprising a first user preference profile corresponding to a first user of at least one device of the plurality of devices in the specific space and a second user preference profile corresponding to a second user of the at least one device in the specific space; and determining the priorities of the devices based on the first user preference profile or the second user preference profile based on which of the first user or the second user is in the specific space at a time of the demand response, and wherein generating the respective participation profiles for the devices comprises: receiving outdoor temperature data; and generating, for at least one of the devices, a first participation profile having a first energy savings rate based on the outdoor temperature being greater than or equal to threshold value and a second participation profile having a second energy savings rate greater than the first based on the outdoor temperature being less than the threshold value.

9. A demand response system comprising: a controller configured to determine priorities of devices to be controlled to participate in a demand response, extract user preference profiles of the devices through machine learning by using past using histories of the devices in a specific space, the user preference profiles comprising a first user preference profile corresponding to a first user of at least one device of the plurality of devices in the specific space and a second user preference profile corresponding to a second user of the at least one device in the specific space, generate respective participation profiles for the devices based on the determined priorities, and change the priorities of the devices included in the participation profiles, based on whether participation in the demand response according to the generated participation profiles succeeds; and a communication unit configured to transmit control signals of the controller to the devices, wherein the controller determines the priorities of the devices based on the first user preference profile or the second user preference profile based on which of the first user or the second user is in the specific space at a time of the demand response, and wherein generating the respective participation profiles for the devices comprises: receiving outdoor temperature data; and generating, for at least one of the devices, a first participation profile having a first energy savings rate based on the outdoor temperature being greater than or equal to threshold value and a second participation profile having a second energy savings rate greater than the first based on the outdoor temperature being less than the threshold value.
